Description

Technical Field

[0001] This utility model relates to the field of orthodontic technology, and in particular to an orthodontic appliance for correcting molar mesial and lingual inclination. Background Technology

[0002] With the development of the current social economy and the popularization of oral health care knowledge, more and more people are aware of the harm of long-term tooth loss. The improvement and perfection of the medical insurance system have led to more and more dental crowns and implants being covered by medical insurance, giving people the financial means to afford corresponding tooth replacement measures. Consequently, more and more people are paying attention to the restoration of their missing teeth. However, due to long-term tooth loss or malocclusion before surgery, abnormal biting forces can cause varying degrees of axial misalignment of the abutment teeth. If this abnormal axial tilt is not corrected before restoration, it may lead to incomplete recovery of chewing function, food impaction, and loosening of the abutment teeth, among other adverse factors. Therefore, correcting the abnormal axial misalignment of the abutment teeth has become a top priority before restoration.

[0003] Currently, for patients with abnormal axial tilt of abutment teeth (mesiodistal tilt, labial-lingual tilt), the existing routine treatment options include:

[0004] 1. Locally bonded brackets can be used to correct abnormal axial tilt of the abutment teeth after the archwire is aligned. However, this approach requires the orthodontist to have certain orthodontic expertise to ensure proper bracket placement and prevent archwire slippage. Furthermore, bracket bonding takes time, and the presence of metal foreign bodies can cause discomfort, potentially exacerbating patient discomfort. Additionally, thorough hygiene is required during treatment, and the constant insertion and replacement of the archwire takes time, resulting in a relatively long treatment period.

[0005] 2. After bonding the abutment tooth to the lingual side and cladding it, a local anchorage screw with rubber chain is implanted for traction. However, anchorage screw implantation requires additional costs, and the surgeon needs a high level of expertise to reduce the occurrence of a series of adverse complications after implantation (anchorage screw dislodgement, intraoperative infection, etc.).

[0006] 3. A cast banded traction arm appliance is fabricated using the remaining non-treatment lateral abutment teeth in the dentition. After intraoral bonding and retention, a rubber chain is used to pull the abutment teeth to adjust their axial inclination. The cast banded traction arm is relatively large, resulting in a more noticeable foreign body sensation. Because the abutment teeth in the patient's mouth vary, bonding is required for retention. The bonding material depends on the intraoperative preparation and may easily fall off or be difficult to remove, and cleaning is also challenging.

[0007] In this context, we need a device that is less sensitive to the orthodontic skills of the operating physician, more comfortable for the patient, minimizes chairside operation time, and is quick and convenient. Utility Model Content

[0008] In view of this, the purpose of this utility model is to provide an orthodontic appliance for correcting mesial and lingual inclination of molars, so as to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model adopts the following technical solution: an orthodontic appliance for correcting mesial and lingual inclination of molars, comprising an orthodontic archwire, wherein the orthodontic archwire includes a fixed part, one or more looped parts and hooked parts; the fixed part is connected to two or more rubber seats, the rubber seats are fixed to the anchor teeth, the hooked part is located at one end of the orthodontic archwire and is located on the buccal side of the tooth to be corrected, the lingual side of the tooth to be corrected is provided with a lingual buckle, the hooked part is connected to a rubber chain, the rubber chain passes around the tooth to be corrected and is connected to the lingual buckle.

[0010] Furthermore, the rubber chain is provided with a plurality of connecting holes evenly distributed therethrough, which are connected to the hook portion of the orthodontic archwire and the tongue-side buckle.

[0011] Furthermore, the curvature of the orthodontic archwire matches the buccal arc formed by the anchorage tooth and the tooth to be corrected installed intraorally.

[0012] Furthermore, the adhesive base is made of resin and is used to bond the fixing part of the orthodontic archwire to the buccal side of the anchor tooth.

[0013] Furthermore, the outer surface of the adhesive base is arc-shaped.

[0014] Beneficial effects

[0015] Compared to existing technologies, this invention offers at least the following advantages: The curvature of the orthodontic archwire can be bent based on a pre-existing dental mold, improving intraoral fit and minimizing patient follow-up and treatment time. The fixing portion of the archwire is bonded to the buccal side of the pre-selected anchorage tooth via a rubber base, achieving a rigid connection and reducing the foreign body sensation on the tooth surface compared to traditional bracket fixation. The outer surface of the rubber base has a rounded structure, which helps maintain the patient's oral cavity. A rubber chain connects the hook portion of the archwire to the lingual fastener fixed to the tooth to be corrected. Because the end of the archwire is free and has a certain degree of resilience, it can apply light and continuous force, achieving elastic traction on the tooth to be corrected and further reducing trauma to the abutment teeth and root resorption. This invention is low-cost, simple to operate, requires less sensitivity to the orthodontic technique of the operator, avoids the use of implants, is more non-invasive, reduces patient discomfort, and maintains the original stable occlusion of the teeth.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] See Figures 1-3 This embodiment provides an orthodontic appliance for correcting mesial and lingual inclination of molars, including an orthodontic archwire 5. The archwire 5 includes a fixed portion 50, one or more loop portions 51, and hook portions 52. The fixed portion 50 is connected to two or more adhesive bases 4. One side of the edentulous area is the tooth to be corrected 2, and the other side is the selected anchorage tooth 1. Each adhesive base 4 is bonded to an anchorage tooth 1. The hook portion 52 is located at one end of the orthodontic archwire 5 and is located on the buccal side of the tooth to be corrected 2. A lingual buckle 7 is provided on the lingual side of the tooth to be corrected 2. The hook portion 52 is connected to a rubber chain 6, which passes around the tooth to be corrected 2 and is connected to the lingual buckle 7.

[0024] The rubber chain 6 has multiple evenly spaced connecting holes 60, which allow for detachable hook-and-loop connection with the hook portion 52 of the orthodontic archwire 5 and the lingual buckle 7. The curvature of the orthodontic archwire 5 matches the buccal arc formed by the anchor tooth 1 and the tooth to be corrected 5 in the mouth. The loop portion 51 is located on one side of the edentulous site 3.

[0025] The adhesive base 4 is made of resin, and through the adhesive properties of the resin itself, the fixing part 50 of the orthodontic archwire 5 can be bonded to the buccal side of the anchor tooth 1. The outer surface of the adhesive base 4 is arc-shaped.

[0026] In practice, the curvature of the orthodontic archwire can be bent according to a pre-existing model taken from the oral cavity, improving intraoral fit and minimizing follow-up visits and treatment time. The fixing part 50 of the orthodontic archwire 5 is bonded to the buccal side of two or three pre-selected anchorage teeth 1 via two or three adhesive bases, achieving a rigid connection of the orthodontic archwire. Compared with traditional bracket fixation, this reduces the foreign body sensation on the tooth surface. The outer surface of the adhesive base has a rounded structure, which is beneficial for maintaining the patient's oral cavity. The lingual side of the tooth to be corrected is fixed with a lingual clip 7 by adhesive. A rubber chain 6 connects the hook part 52 of the orthodontic archwire 5 to the lingual clip, and the rubber chain 6 passes around the tooth to be corrected 2. Because the hook part at the end of the orthodontic archwire is free and has a certain degree of resilience, it can apply light and continuous force, achieving elastic traction on the tooth to be corrected, and further reducing trauma to the abutment teeth and root resorption.

[0027] During orthodontic treatment, the archwire does not need to be removed. The archwire can be applied periodically and more easily using existing oral tools inside the mouth to adjust its angle. This facilitates changes in the traction force of the rubber chain, making the correction of abnormal axial tilt of the teeth to be corrected faster.

[0028] A variety of archwire sizes are available to provide different force bases. In this embodiment, a square archwire is selected, which is made of stainless steel wire with a square cross-section of 0.019 x 0.025 inches.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
